[0026] The utility model will be further illustrated by the embodiment in combination with the drawings, but the utility model is not limited in the embodiment range.

[0027] As Figures 1-3 shown, the embodiment provides an ignition assembly 100, the ignition assembly 100 is used for the ignition of burner, and the ignition assembly 100 includes ignition needle 110, induction needle 120 and cleaning agent delivery pipe 140, the ignition needle 110 and induction needle 120 are hollow, and the surface of the ignition needle 110 and induction needle 120 is provided with clean flow channel 161 penetrating the wall surface of the ignition needle 110 and induction needle 120 along the extension direction of the ignition needle 110 and induction needle 120, and the cleaning agent delivery pipe 140 is connected to the flow channel and is used to deliver cleaning agent to the clean flow channel 161.

[0028] The ignition assembly 100 forms the clean flow channel 161 on the surface of the ignition needle 110 and the induction needle 120, and delivers the cleaning agent to the ignition needle 110 and the induction needle 120 through the cleaning agent delivery pipe 140, the cleaning agent flows out from the clean flow channel 161, thereby cleaning the surface of the ignition needle 110 and the induction needle 120, removing the carbon deposition on the surface of the ignition needle 110 and the induction needle 120, so that the self-cleaning of the ignition needle 110 and the induction needle 120 can be realized.

[0029] ​The ignition assembly 100 further comprises a pumping device (not shown) connected to the cleaning agent delivery pipe 140 to pump the cleaning agent into the cleaning agent delivery pipe 140.

[0030] The ignition assembly 100 further comprises a cleaning agent storage tank (not shown) to store the cleaning agent, from which the pumping device pumps the cleaning agent into the cleaning agent delivery pipe 140.

[0031] The ignition assembly 100 further comprises a grounding needle 130, the surface of which is also provided with a cleaning flow channel 161. In other embodiments, the ignition assembly 100 can not comprise the grounding needle 130.

[0032] The ignition assembly 100 further comprises a mounting portion 150, on which the ignition needle 110 and the induction needle 120 are mounted; the ignition needle 110 and the induction needle 120 are inserted through the mounting portion 150.

[0033] The mounting portion 150 is generally made of insulating materials such as ceramics to avoid leakage or short circuit.

[0034] The mounting portion 150 is provided with a communication passage 151, which is in communication with the cleaning agent delivery pipe 140 and the cleaning flow channel 161 respectively. The contact part of the communication passage 151 with the cleaning agent delivery pipe 140 is trumpet-shaped to decompress and rectify the cleaning agent.

[0035] The cleaning agent in the cleaning agent delivery pipe 140 is delivered into the cleaning flow channel 161 through the communication passage 151 in the mounting portion 150.

[0036] The ignition needle 110 and the induction needle 120 have the cleaning flow channel 161 at the part of the first side of the mounting portion 150, and the cleaning agent delivery pipe 140 is connected to the second side of the mounting portion 150, the first side being opposite to the second side.

[0037] The cleaning agent delivery pipe 140 is on the opposite side of the ignition site of the ignition needle 110 and the induction needle 120, so as to avoid interfering with the ignition of the ignition needle 110 and the induction needle 120.

[0038] The surface of the ignition needle 110 and the induction needle 120 is further provided with a plurality of cleaning holes 162 penetrating the wall surface of the ignition needle 110 and the induction needle 120, and the plurality of cleaning holes 162 are arranged on both sides of the cleaning flow channel 161 along the extension direction of the cleaning flow channel 161.

[0039] The cleaning flow channel 161 is provided with the cleaning holes 162 on both sides, when the cleaning agent reaches the hole position, the cleaning agent flows out of the cleaning holes 162 by the action of surface tension and friction force, and the cleaning agent will flow along the surface of the ignition needle 110 or the induction needle 120 for cleaning.

[0040] The hole diameter of the cleaning hole 162 near the ignition end 111 of the ignition needle 110 and the induction needle 120 is larger than the hole diameter of other cleaning holes 162 on the ignition needle 110 and the induction needle 120.

[0041] The end of the ignition needle 110 and the induction needle 120 is prone to carbon deposition, and the hole diameter of the cleaning hole 162 is increased here. When only the easily oxidized area needs to be cleaned, the flow is reduced. Because the cleaning hole 162 of the easily oxidized area is lower in height, the cleaning agent will only pass through the cleaning hole 162 of this area and will not flow out from other positions, achieving separate cleaning of the easily oxidized area and saving the amount of cleaning agent used.

[0042] The ignition assembly 100 is provided with a cleaning flow channel 161 on the surface of the ignition needle 110, the induction needle 120, and the grounding needle 130. The cleaning agent flows into the cleaning flow channel 161 of the ignition needle 110, the induction needle 120, and the grounding needle 130 via the cleaning agent conveying pipe 140 and the communication passage 151 (the contact part of the communication passage 151 and the cleaning agent conveying pipe 140 is trumpet-shaped, which reduces and rectifies the cleaning agent). The two sides of the cleaning flow channel 161 are provided with cleaning holes 162. When the cleaning agent reaches the cleaning hole 162, the cleaning agent flows out of the cleaning hole 162 by surface tension and friction, and the cleaning agent flows along the surface of the ignition needle 110, the induction needle 120, and the grounding needle 130 to clean.

[0043] The communication passage 151 of the mounting part 150, the cleaning flow channel 161 of each part of the ignition needle 110, the induction needle 120, and the grounding needle 130 cooperate to achieve full-position flow of the cleaning agent, greatly solving the problem that the ignition induction needle 120 cannot be self-cleaned.

[0044] By arranging cleaning holes 162 with different heights and sizes on both sides of the cleaning flow channel 161, the cleaning holes 162 of the ignition end 111 or other easily oxidized areas of the ignition needle 110, the induction needle 120, and the grounding needle 130 are arranged to be lower in height or larger in size. The cleaning agent in the flow channel will tend to flow to the easily oxidized part for deep cleaning. When full-segment cleaning is required, the flow of the cleaning agent is adjusted to the maximum (the pumping power is adjusted to the maximum), and because the size of the cleaning hole 162 is small, the cleaning agent will fill the flow channel, and the cleaning agent will flow out of each cleaning hole 162. When only the easily oxidized area needs to be cleaned, the flow is reduced (the pumping power is reduced). Because the cleaning hole 162 of the easily oxidized area is lower in height, the cleaning agent will only pass through the cleaning hole 162 of this area and will not flow out from other positions, achieving separate cleaning of the easily oxidized area and saving the amount of cleaning agent used.
